Postdoc in Multi-Fidelity Models for Vascular Problems

School of Engineering Sciences at KTH

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

Job description

As part a cross-department initiative, the department of Engineering Mechanics announces a postdoc position within the thematic area “Advanced computing and machine learning” on the topic of multi-fidelity models for vascular problems. The postdoc will be working on developing advanced methods for multifidelity simulations within the application area of vascular biomechanics. This includes the theoretical development, implementation into open-source codes, and coupling to existing vascular simulation methods. The goal is to combine experimental observations and high-fidelity simulations with low-fidelity (low-order) models to make accurate predictions for the biomechanical quantities of interest. The multifidelity models can also be very useful for uncertainty quantification (UQ) and optimisation.

We thus want to combine novel UQ techniques for multi-fidelity models with state-of-the-art simulation techniques (reduced-order models, RANS, LES) of clinical realistic  hemodynamic problems. The proposed inclusion of the simultaneous prediction of uncertainty of the fused results is a completely novel approach in the field. The multidisciplinary nature of the project allows for publications with different scope ranging from fundamental method and software development, to clinical biomechanical applications. Given the importance of cardiovascular diseases, the potential outcomes are also of high socioeconomic relevance.

This position is one of eight postdoc positions in the thematic areas

Biomechanics, Health and Biotechnology

Advanced Material and Structures, Energy

Transport and Future Mobility, and

Advanced Computing and Machine Learning.

What we offer

  • A position at a leading technical university that generates knowledge and skills for a sustainable future
  • Engaged and ambitious colleagues along with a creative, international and dynamic working environment
  • Works in Stockholm, in close proximity to nature
  • Help to relocate and be settled in Sweden and at KTH
  • Existing simulation codes for vascular turbulent flows, and methods for UQ and reduced-order models.
  • Access to HPC computing and data resources within Sweden and Europe.
  • Multidisiplinary research group, including experts from simulation, UQ, fluid dynamics and vascular flows and tissues.
